12. 12 Challenges Very demanding timeline, few break points to pause Once the cells are thawed extremely strict margins to fulfill Planning: days with dense timetable for crew

13. 13 BIOTESC PoC: bernd.rattenbacher@hslu.ch SPHEROIDS

14. 14 SPHEROIDS – Experiment Overview Scientific Aims: comparing the effects of real microgravity to those induced by mimicked weightlessness on the RPM evaluating the protective effect of VEGF against potential apoptosis post-flight analysis of three dimensional cell assembly, differentiation and apoptosis H/W upload: SpX-7: KUBIK Interface Plates (KIPs) (lost) SpX-8: SPHEROIDS Experiment Containers 2x 8x

15. 15 Impact of SpX-7 Loss and Spheroids Flight Readiness 2 KIPs can be replaced by 1 spare FM and upgrade of 1 QM (upgrade feasible in 3-5 months) 2 KIPs need to be uploaded before the Experiment H/W KUBIK 6 is at the moment not operational due to expired batteries in centrifuge eBox 2 KUBIK eBoxes were lost on SpX-7 Refurbished eBoxes from KUBIK 3 will have to replace the lost ones and be integrated in KUBIK 6 before the experiment

16. 16 KUBIK Overview D1D2 KUBIK Interface Plates (KIPs) – installed at least 1 day before experiment start KUBIK 5 – 39 hours incubation at 37˚C => MELFI cold stowage KUBIK 6 – 8.5 days incubation at 37˚C => change of temperature to 6˚C and cold stowage in KUBIK up to 30 days

17. 17 Experiment Activities -Day 0 Big picture words KUBIK 5 setup & KIP installation, KUBIK 6 setup & KIP instalation -Day 1 Experiment installation in KUBIK 5 and KUBIK 6 -Day 3 Experiment removal from KUBIK 5 & transfer to MELFI -Day 3 – 9 KUBIK 5 datacopy Regular checks of KUBIK 6 temperature (37 ˚C ) -Day 10 KUBIK 6 datacopy Setting KUBIK 6 to 6 ˚C -Day 10 - download Regular checks of KUBIK 6 temperature (6 ˚C ) - Download day Experiment removal from KUBIK 6 and MELFI and packing -1 day after download KUBIK 6 datacopy 2 SPHEROIDS- KUB5-SU SPHEROIDS- KUB6-SU KUB5-KIP- INST KUB6-KIP- INST SPHEROIDS-KUB-PREP SPHEROIDS-EC-INST SPHEROIDS- KUB5-DEINST SPHEROIDS- KUB5- DATACOPY SPHEROIDS- KUB6- DATACOPY INCUBATION at 37˚C 39 hrs INCUBATION at 37˚C 207 hrs SPHEROIDS- COOLTEMP SPHEROIDS- KUB6-DEINST SPHEROIDS-EC-PACK SPHEROIDS- KUB6- DATACOPY 2

18. Challenges / Watch Outs i.Time constraints are given by the automatic, pre-programmed timeline in the EC: i.Removal of EC before end of experiment run will lead to complete loss of science (no fixation) ii.In case of KUBIK power loss the timeline is interrupted by the duration of the power loss –> de-installation activity (for ECs in KUBIK 5) and/or setting of KUBIK to 6°C activity (ECs in KUBIK 6) to be shifted in the timeline accordingly iii.The experiment run between EC installation and removal/cold stowage activity is 39hrs/207hrs: EC installation and EC removal/cold stowage activity need to be coordinated such that they fit in the crew day ii.In case of KUBIK anomaly the recovery action shall be started as soon as possible: gradual loss of sample viability and complete loss of science after 12 hours
